A nationwide school examination in history included several multiple-choice questions. Each question had 4 possible answers, only one of which was correct. In a sample of 1000 students from more than 100000 students who participated in the test it was found that 38% answered the first multiple- choice question correctly. Assume that if a student knew the answer to this question then with 100 percent chance he chose the right answer. If a student didn't know the answer, he tried...
